修复方式：

4.1系统加载的网页若可能出现异常则占时关闭Js，规避Crash

 /**
     * fix 4.1系统加载网页时出现IllegalArgumentException
     */
    public static void disableJsIfUrlEncodedFailed(IWebView webView, String url){
        if(Build.VERSION.SDK_INT != 16) {return;}
        try {
            URLEncodedUtils.parse(new URI(url), null);
            webView.getSettings().setJavaScriptEnabled(true);
        } catch (URISyntaxException ignored) {
        } catch (IllegalArgumentException e) {
            webView.getSettings().setJavaScriptEnabled(false);
        }
    }

修复方案：

问题主要集中在4.2.1和4.2.2 ，对此针对性处理：

    /**
     * 关闭辅助功能，针对4.2.1和4.2.2 崩溃问题
